摘　　要：用气相色谱-质谱的选择离子法测定四川省妇女血清中多溴联苯醚的质量浓度,并对其组成特征及主要来源进行了研究.在被测的11种多溴联苯醚当中,BDE-209是主要成分,质量浓度从0.12～2.38μg.L-1,中值为0.63μg.L-1,占多溴联苯醚总量的质量分数为63.57%～90.34%,其次是BDE-66、-99和-100,其它多溴联苯醚几乎没有检出,表明污染主要来自十溴联苯醚,其次是四溴和五溴联苯醚.实验结果与其它国家的数据相比,表明多溴联苯醚对普通妇女的污染在四川还处于一个较低的水平.The serum concentrations of polybrominated diphenyl ethers（PBDEs） in women from Sichuan province were detected via gas chromatograph-mass spectrometry in selected ion monitoring mode（SIM）.Based on the experimental data,the compositions and distribution characteristics of PBDEs as well as pollution resource were also explored.Among these 11 congeners of PBDEs detected,BDE-209 was the dominant congener accounting for 63.57%-90.34% in the total PBDEs,followed by BDE-66,-99 and-100.The concentrations of BDE-209 ranged from 0.12 to 2.38 μg·L^-1and the mean concentration was 0.63 μg·L^-1.Other congeners of these 11 PBDEs could not be detected.The data indicated that the major pollution came from deca-BDE,followed by tetra-BDE and penta-BDE.At the mean time,this result also showed that the pollution of PBDEs in Sichuan province was still at a lower level for ordinary women when compared to the data from other countries.
